FREEZER OR REFRIGERATOR.

SPECIFICATION forming part of Letters Fatent No. 416,417, dated December 3, 18 89.

Application filed July 26, 1889- at Ogdensburg, in the county of St. Lawrence and State of New York, have invented a new and useful Improvement in Freezers or Refrigerators, of which the following is a specification.

This invention relates to improvements in freezers or refrigerators for making ice .and preserving articles of food; and it consists in the construction, combination, and arrangement of parts, as will be hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a perspective view. Fig. 2 is a vertical crosssection on the line as at, Fig. 1. Fig. 3 is a horizontal section on the line y y, Fig. 1.

Similar letters of reference indicate corre sponding parts.

A represents the outer case of the freezer, which may be of any desired shape or size and is constructed of wood or other suitable material. This case is provided with an inner wall or lining B of wood, so arranged as to leave a space a between the walls, which is filled with sawdust or other non-conducting material.

0 represents a freezing or cooling chamber, the walls of which are constructed of metal. At the sides and back of the cooling-chamber is arranged a refrigerant-chamber D, in which is placed a mixture of ice and salt. The inner walls of the ice-chamber are formed by the outer sides of the cooling-chamber and the outer walls by a metal partition I), which extends from the bottom of the refrigerator nearly to the top or cover I. The ice-chamber may be made in three parts, if desired, forming separate chambers arranged, respectively, at the sides and back of the coolingchamber.

Between the outer wall I) of the ice-chamber and the lining B of the case is formed a space or chamber E, whichis filled with common dry salt. The salt is used to absorb moisture, and also by its non-conducting properties to assist in preserving the ice in the chamber D. I have found that salt is the best material for this purpose, although, if desired, other non-conducting substances may be used.

Serial No. 318,771. (No model.)

The bottom G of the freezermay be made with double walls, like the sides, the intervening space being filled with non-conducting material.

Small tubes or openings 0, leading from the ice-chamber, extend through the bottom of the freezer for the escape of water formed from the melting ice.

The external case A is provided with a hinged lid or top cover H and an under cover I. In the under cover I are formed apertures 0r feeding-holes cl, through which the salt and the mixture of ice and salt are placed in the chambers E and D.

J represents covers or lids for closing the feeding-holes in the top I. The top cover or lid H has downwardly-projecting flanges,

which, when the lid is closed, assist in excluding the air more effectually from the freezer.

K is the door of the cooling-chamber O. This door, as well as the lids J and the cover H, may be provided with packing, so as to form air-tight closures.

After the mixture of ice and salt is placed in the chamber D, a quantity of laundrybluing dissolved in water is poured over it, forming a cement or crust e, which by excluding the air assists in preserving the ice. Other materials may be used for coating the ice; but I have found by repeated experiments that bluing is the best material for this purpose. By'this construction and arrangement a very low temperature is produced, and water placed in pans and introduced into the chamber O is readily converted into ice. A portion of the ice thus formed can be used for keeping the freezer in operation. The apparatus can also be used as a refrigerator, and articles of food, as meat, fish, milk, &c., can be economically preserved.

Having thus described my invention, whatI claim as new, and desire to secure byLetters Patent, is-

1. In a freezer or refrigerator, the combination, with a double-Walled outer case filled with non-conducting material, of the salt tank orchamber arranged within the case, a refrigerant or ice chamber inside of the salt chamber having a door in front. a refrigerant or ice chamber at the sides and back of the cooling-chamber, a salt-tank arranged outside of said refrigerant-chamber, and an external case provided with feed-holes for filling the refrigerant and salt tanks, substantially as shown and described.

3. In a freezer or refrigerator, a chamber for the reception of articles to be cooled or I0 frozen, a tank or chamber arranged outside of the cooling-chamber, a refrigerant contained in said tank, a cement or coating forming an air-tight covering for said refrigerant, a cover provided with holes for filling said refrigerant-tank, and lids for closing said 15 holes, substantially as herein set forth.
